• Architectural Design

An architectural model is a rich and rigorous diagram, created using available standards, in which the primary concern is to illustrate a specific set of tradeoffs inherent in the structure and design of a system or ecosystem. Software architects use architectural models to communicate with others and seek peer feedback. An architectural model is an expression of a viewpoint in software architecture.

• Logical View

The logical view is concerned with the functionality that the system provides to end-users. UML diagrams used to represent the logical view include, class diagrams, and state diagrams or which shows the key abstractions in the system as objects or object classes.

• Process View

The process view deals with the dynamic aspects of the system, explains the system processes and how they communicate, and focuses on the runtime behavior of the system.

The process view addresses concurrency, distribution, integrators, performance, and scalability, etc. UML diagrams to represent process view include the activity diagram.
Activity diagrams are graphical representations of workflows of stepwise activities and actions with support for choice, iteration and concurrency.
In the Unified Modelling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities. Although activity diagrams primarily show the overall flow of control, they can also include elements showing the flow of data between activities through one or more data stores

• Development View

The Development Viewpoint is a considerable amount of planning and design of the development environment is often required to support the design and build of software for complex systems. It is the role of the Development view to address these aspects of the system development process.

Definition	Describes the architecture that supports the software development process.
Concerns	module organization common processing standardization of design standardization of testing instrumentation codeline organization
Models	module structure models common design models codeline models
Pitfalls	too much detail overburdening the AD uneven focus lack of developer focus lack of precision problems with the specified environment
Stakeholders	Production engineers, software developers and testers.
Applicability	All systems with significant software development involved in their creation.

• Physical View

The physical view depicts the system from a system engineer's point of view. It is concerned with the topology of software components on the physical layer as well as the physical connections between these components. This view is also known as the deployment view. UML diagrams used to represent the physical view include the deployment diagram. The following diagram is the UML deployment diagram:

• Scenario

The description of an architecture is illustrated using a small set of use cases, or scenarios, which become a fifth view. The scenarios describe sequences of interactions between objects and between processes. They are used to identify architectural elements and to illustrate and validate the architecture design. They also serve as a starting point for tests of an architecture prototype. This view is also known as the use case view. The following diagram is the use case view.
